Implementing Create(), with the capability of random writing (for example like
being needed by gdalwarp or nearblack), is not doable due to the nature of PDF.
But as CreateCopy() is already implemented, you can for example create a
in-memory raster (see the MEM driver) and CreateCopy() it into a geospatial PDF.
